Device for localization of stereotactic coordinates

Abstract

The invention concerns a device for localization of stereotactic coordinates by available MRI, CT, PET and angiogram imaging equipment in relation to known art animal stereotactic frames comprised of a pair of bars held in spaced parallel relation to each other by a cross bar that may be fixed to an operating table or the like by means of a fixing device, which connects to the instrument. The instrument may be detached from the stereotactic frame to allow for the imaging procedures. The instrument is made of non-magnetic and radiolucent material allowing for the use of magnetic material and radio-opaque stereotactic frames in combination with available MRI, CT, PET, and angiogram imaging equipment.

1 . A device for localisation of stereotactic coordinates for identifying a spatial position of a region of interest in an individual's skull for the performance of stereotactic procedures, said device comprising a box of non-magnetic, radiolucent material with fiducial markers and said device being attachable to a stereotactic frame.  
   
   
       2 . A device according to  claim 1 , wherein said fiducial markers includes scull fixation pins projecting inwardly into the interior space of the box.  
   
   
       3 . A device according to  claim 1  (or  2 ], wherein said box including at least one attachable side plate means made of translucent or transparent and radiolucent material.  
   
   
       4 . A device according to  claim 3 , wherein said at least one side plate means further including fiducial reference lines allowing for identification of an area of interest.  
   
   
       5 . A device according to any of tho preeding claims  claim 1 , wherein said device comprises a nose fixation clamp.  
   
   
       6 . A device according to any of tho preceding ClaiLL  claim 1 , wherein said device is adapted to fit like a drawer under the stereotactic frame, when being attached thereto.  
   
   
       7 . A device according to any of tho preceding claims  claim 1 , wherein said box comprises a top part and a bottom part fitting together with a ridge and groove in the sides of the top part and the bottom part.  
   
   
       8 . A device according to  claim 7 , wherein said box is provided with a locking mechanism to allow for the top and bottom parts being fixed to each other.
